The following steps will make your experience with the BBS better:

Set the Encoding to IBM437 (You'll have to scroll down a bit for this)

Set the Emulation to ANSI

Set the Special Keys to On

If you want to use ssh, use the account: and you will need
to authenticate with the password shsbbs (after that, log in normally).

dots in the upper right corner) to 80x25 TWICE.  For some reason, the first
time doesn't set the length of the screen properly.  Turn on the keyboard,
and have fun!
